I just picked up this vintage Dixco tach. It has only two wires. I was reading that one wire goes to power for light and the other to the negative side of the coil-and that it grounds on the mounting.
I have also read conflicting stuff about whether it will work with electronic ignition-is this true?
anyone have any experience installing these?
I love the look of the tach and would like to use it.
